but for one thing, a much larger portion of her act is about her own stuff (female, jew) than about other races. So Kamau's misrepresenting it factually.

Silverman's humor comes not from how shocking the things she says are, but because it's a satire of the way that racism becomes almost banal in contemporary society. What's funny is the contrast between how hateful the things she says are and how much we want to like her because she seems like a nice, pretty girl. The joke is on us and our expectations.

As opposed to say Carlos Mencia or Andrew Dice Clay, where the joke is "this is what we're all thinking, but are too PC to say." Which of course is bullshit.

She's also a much more talented comedian than those two guys, and she's night and day more talented than Larry the Cable Guy.
